Struct QueryRuntimeContext 

pub struct QueryRuntimeContext {
    pub instance_id: String,
    pub query_id: String,
    pub update_tx: ComponentUpdateSender,
}

Context provided to Query components during initialization.

Contains the DrasiLib instance ID and update channel for status reporting. Constructed by QueryManager when a query is added via add_query().

Unlike sources and reactions, queries are internal to drasi-lib (not plugins), but still follow the same context-based initialization pattern for consistency.

Clone

This struct implements Clone and uses Arc internally for the update channel, making cloning cheap (just reference count increments).

Fields

instance_id: String

DrasiLib instance ID (for log routing isolation)

query_id: String

Unique identifier for this query instance

update_tx: ComponentUpdateSender

mpsc sender for fire-and-forget component status updates.

Status changes sent here are applied to the component graph by the graph update loop, which emits broadcast events to all subscribers.

Implementations

impl QueryRuntimeContext

pub fn new( instance_id: impl Into<String>, query_id: impl Into<String>, update_tx: ComponentUpdateSender, ) -> Self

Create a new query runtime context.

This is typically called by QueryManager when adding a query to DrasiLib.

Arguments

• instance_id - The DrasiLib instance ID
• query_id - The unique identifier for this query
• update_tx - mpsc sender for status updates to the component graph

pub fn instance_id(&self) -> &str

Get the DrasiLib instance ID.

pub fn query_id(&self) -> &str

Get the query’s unique identifier.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryRuntimeContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result
